Creating Intelligent Content with Lightweight DITA documents the evolution of the Darwin Information Typing Architecture (DITA) - a widely used open standard for structuring technical content. DITA has grown in popularity and features since its origins as an internal grammar for structuring technical documentation at IBM. This book introduces Lightweight DITA (LwDITA, which should be read as "Lightweight DITA") as a proposed version of the DITA standard that reduces its dependence on complex Extensible Markup Language (XML) structures and simplifies its authoring experience. This volume aims to reconcile discrepancies and similarities in methods for authoring content in industry and academia and does so by reporting on DITA's evolution through the lens of computational thinking, which has been connected in scholarship and media to initiatives for learning to code and programming. Evia's core argument is that if technical communicators are trained with principles of rhetorical problem solving and computational thinking, they can create structured content in lightweight workflows with XML, HTML5, and Markdown designed to reduce the learning curve associated with DITA and similar authoring methodologies. At the same time, this book has the goal of making concepts of structured authoring and intelligent content easier to learn and teach in humanities-based writing and communication programs. This book is intended for practitioners and students interested in structured authoring or the DITA standard.

IT-Projekte haben in vielen Unternehmen eine zentrale Bedeutung. Sie binden Ressourcen und generieren entsprechende Kosten. Im Durchschnitt werden in Unternehmen 33 Projekte pro 1000 Mitarbeitern durchgefuhrt und pro Mitarbeiter und Jahr EUR 8.000 in IT-Projekte investiert. Von diesen Projekten werden weniger als die Halfte erfolgreich abgeschlossen.

An theoretischem Wissen respektive an der Ausbildung kann es nicht liegen. Aus Sicht der Autoren fehlt es den Projektmanagern oft an der notwendigen Reflexion, dies besonders wenn die Projekte in kritische Phasen treten. Ein Erfahrungsaustausch zwischen den Projektleitern findet vielfach aus zeitlichen Grunden nur unvollkommen statt. Hier setzen die Autoren an. Sie legen das Schwergewicht auf die kritischen Erfolgsfaktoren eines IT-Projekts. Gegliedert nach Erfolgsfaktoren fuhrt das Buch zum Thema und veranschaulicht Losungswege anhand von Beispielen aus der Praxis.

Smart web developers will tell you that the sooner you detect your code mistakes, the quicker you can fix them, and the less the project will cost in the long run. Well, the most efficient way to detect your mistakes in PHP is with PHPUnit, an open source framework that automates unit testing by running a battery of tests as you go. The benefits of PHPUnit are significant, they are: a reduction in the effort required to frequently test code; fewer overall defects; added confidence in your code; and improved relations with your open source teammates. The only problem with this popular testing tool was its lack of documentation-until now, that is. For this, "O'Reilly" went right to the source, as Sebastian Bergmann, the author of "PHPUnit Pocket Guide", also happens to be PHPUnit's creator. This little book brings together hard-to-remember information, syntax, and rules for working with PHPUnit. It also delivers the insight and sage advice that can only come from the technology's creator. The coverage of testing under agile methodologies and Extreme Programming (XP) is also included. The latest in "O'Reilly's" series of handy Pocket Guides, this quick-reference book puts all the answers are right at your fingertips. It's an invaluable companion for anyone interested in testing the PHP code they write for web applications.

Performance is a hugely important area of web development. If your site runs slowly, users are going to leave, and the problem only grows as your site gets more popular. Pro JavaScript Performance gives you the tools you need to keep your sites smooth and responsive no matter how many users you have. Best practices are changing or becoming redefined continually because of changes and optimizations at the interpreter level, and differences in system configuration, and network speeds. This is exacerbated by the quickened release schedule that most browsers have adopted. Just as important as following best practices is the ability to measure your own performance, so that you can adjust as times change, and so that you can note the subtle nuances in your own code and define your own best practices by your own observations. This book gives you the tools to observe and track the performance of your web applications over time from multiple perspectives, so that you are always aware of, and can fix, all aspects of your performance.What you'll learn * Describes the different aspects of performance, and explores the tools for quantifying and improving performance * Provides tactical solutions for creating tools to measure the performance of your own web applications * Learn to apply performance best practices, and how to quantify your results Who this book is for Pro JavaScript Performance is written for advanced JavaScript users and web developers.

The emergence of the cloud and modern, fast corporate networks demands that you perform judicious balancing of computational loads.Practical Load Balancing presents an entire analytical framework to increase performance not just ofone machine, but of your entire infrastructure. Practical Load Balancing starts by introducingkey concepts and the tools you'll need to tackle your load-balancing issues. You'll travel through the IP layers and learnhow they can create increased network traffic for you. You'll seehow to account for persistence and state, and how you can judge the performance of scheduling algorithms. You'll then learn how to avoid performance degradation and any risk of the sudden disappearance of a service on a server.If you're concerned with running your load balancer for an entire network, you'll find out how to set upyour network topography, and condense each topographical variety into recipes that will serve you in different situations. You'll also learn about individual servers, and load balancers that can perform cookie insertion or improve your SSL throughput. You'll also explore load balancing in the modern context of the cloud. While load balancers need to be configured for high availability once the conditions on the network have been created, modern load balancing has found its way into the cloud, where good balancing is vital for the very functioning of the cloud, and where IPv6 is becoming ever more important. You can read Practical Load Balancing from end to end or out of sequence, and indeed, if there are individual topics that interest you, you can pick up this book and work through it once you have read the first three chapters. What you'll learn Judgenetwork load balancingalgorithms and when to use them Plan your network for optimal load balancing performance Configure single servers to take advantage of modern load balancing software Learning to use load balancing software like HAproxy, STunnel etc. Become familiar with implications of IPv6 and the cloud Improve SSL throughput and seamless application cookie insertion Who this book is for
